By making it mobile, thereby, flow out when on ball 10, adhering in right amount, and then can write as the printing ink 5 of coating fluid inside by ballpoint tip 1 while the ball 10 that pushes the front end that is positioned at ballpoint tip 1.
Ballpoint tip 1 is made up of ballpoint tip main body (tool with point main body) 11, ball 10 and ball pushing member 12 as shown in Figure 2.
Ballpoint tip main body 11, its front is closely coniform in appearance, and it is closely cylindric that rear end side is, and is both bonded rocket shapes in the axial direction on the whole.Front has conus portion 25, and rear end side has cylindrical portion 26.In addition, the rear end side of cylindrical portion 26 has the ink roller junction surface 26a that external diameter slightly dwindles, and is connected with ink roller 6.In addition, pearl pedestal 15, centre hole 16 and metapore 17 are set in the inboard and are communicated with the connection stream of formation printing ink 5.In addition, the rear end side at metapore 17 has rear end side opening 28.
As shown in Figure 3, Figure 4, pearl pedestal 15 has as the cylindrical wall 41 that is the sidewall of cylinder inner wall shape, is positioned at the bearing surface 45 and the joint face 71 of the rear end side of cylindrical wall 41.Joint face 71 is joint faces of cylindrical wall 41 and bearing surface 45.Bearing surface 45 forms by the pressure pearl (tapping) that pushes ball 10 from front end to the back-end as described later, and its section form is circular-arc.
The shape of joint face 71 is that the summit is the side view of the frustum of a cone of front, and the angle [alpha] of the front of the section of this frustum of a cone is 240 ℃.
As shown in Figure 3, Figure 4, around ballpoint tip main body 11 youngsters' centre hole 16.Be radial being provided with and be referred to as the groove 47 of vowing groove.Groove 47 links to each other with pearl pedestal 15, and printing ink 5 by groove 47, passes through the export department 61 of pearl pedestal 15 sides of groove 47 by centre hole 16 again, can flow in the pearl pedestal 15.
Ball pushing member 12 is springs of coiled type, and as shown in Figure 2, ball pushing member 12 is arranged at the inside of ballpoint tip main body 11 with compressed state, and is distolateral forward to ball 10 application of forces from rear end side.Specifically, at front end bar-like portion 23 is set, the top 23a of bar-like portion 23 contacts with ball 10.When the situation that ballpoint pen is not used, can prevent that by above-mentioned exerting pressure above-mentioned printing ink 5 from flowing out to the outside, when using ballpoint pen, ball 10 is moved to the back-end owing to write pressure, printing ink 5 just can flow out easily.
Ball 10 is globular, and the pearl pedestal 15 that is maintained at ballpoint tip main body 11 is interior and rotatable.That is, rear end side is by bearing surface 45, and side is by cylindrical wall 41, front as described later, keep ball 10 by front end crushed element 43, this front end crushed element is after ball 10 inserts, the part that the front end that makes ballpoint tip main body 11 of being closed up is out of shape to the inside.
As shown in Figure 5, have in the ballpoint tip 1 of present embodiment near front end variant part 43 places of the front of the side wall surface 41 of near the gap T export department 61 of groove 47 and ball 10, pearl pedestal 15 and near the gap S2 the ball 10 the most approaching places, ballpoint tip main body 11 and ball 10 between gap S1.
When using ballpoint pen 7, printing ink 5 flow into pearl pedestal 15 from the gap T of centre hole 16 by the export department 61 of pearl pedestal 15 sides of groove 47, and by gap S2, S1 flows to the outside from the gap again.
Gap T, gap S1, gap S2 are by the outer diameter D of ball 10, press the internal diameter etc. of the side wall surface 41 of pearl deflection L, pearl pedestal 15 to determine.
As press pearl deflection L to increase, then gap S1 can become greatly because outside bearing surface front end side edge part 54 is positioned at, near the export department 61 of groove 47 and ball 10 between gap T diminish.In addition, reduce as pressing pearl deflection L, bearing surface front end side edge part 54 then shown in Figure 6 is positioned at the inboard, cause gap T to become big, and gap S1 diminishes.
But, in ballpoint tip 1 of the present invention, because the pressurizing and deformation surface portion 70 of ballpoint tip main body 11 is processed into the part that the summit is the cone surface of front, even press pearl deflection L to increase thus, but because bearing surface front end side edge part 54 is in the inboard, so the gap T of the export department 61 of pearl pedestal 15 sides of groove 47 can become bigger.Therefore the discharge of having stated printing ink 5 of the present invention can be at least 50mg/10m, can also flow out more printing ink 5.Thereby, when writing, can form the person's handwriting of the three-dimensional of surfacing and delustring with it.
In addition, the influence of pressurized pearl deflection L is very little, near side wall surface 41 and the ball 10 the most approaching places gap S2 is made into the certain-length less than gap S1 and gap T, owing to can reduce the circulation of printing ink 5 most effectively by gap S2, so can positively realize adjustment to flow.That is, in the tool in the past,, therefore, just must make S2 narrower, so just can not flow out more coating fluid as utilizing gap S2 that flow is reduced because gap S1 and gap T can not become greatly simultaneously.In addition, as utilize gap S1 and gap T to adjust flow, then can cause fluctuations in discharge, thereby can not realize stable the adjustment owing to the deviation of pressure pearl deflection L.But, ballpoint tip 1 of the present invention, because gap S1 and gap T can become big simultaneously, and can adjust flow by gap S2, therefore also applicable to a tool that flows out more coating fluid, and the discharge of having stated printing ink 5 of the present invention can be at least 100mg/10m, thereby when writing with it, can form the person's handwriting of the three-dimensional of surfacing and delustring.
In addition, as shown in Figure 6, bearing surface side machined surface 48 comprises pressurizing and deformation surface portion 70 and linking part 71, and this pressurizing and deformation surface element 70 deforms by pressing pearl.As shown in Figure 6, by pressing pearl, pressurizing and deformation surface element 70 is subjected to the pressure from ball 10, and deforming becomes bearing surface 45.
The shape of bearing surface side machined surface 48 is to be the lateral shape of the frustum of a cone of front with the summit, is the part of cone surface.In addition, pressurization sex change surface element 70 and linking part 71 are to be the lateral shape of the frustum of a cone of front with the summit too, are the parts of cone surface.Pressurizing and deformation surface element 70 forward end are side-prominent.The cross section angle [alpha] of the front of this frustum of a cone is 240 °, and the medial surface 48a of bearing surface side machined surface 48 is acute angle-shaped.
In addition, in the bearing surface side machined surface 48 of present embodiment, the integral body of pressurizing and deformation surface element 70 forms summit the 1st 85 as the cone surface of front.In addition, because linking part 71 is the parts of not carrying out pressing the pearl distortion, so it is non-pressurizing and deformation surface element 72.

For example, at first form ballpoint tip main body 11.Use columned material, on the profile front side is processed into the conus portion 25 of nearly cone shape, form designated shape (the 1st operation).Then, the structure with a side wall surface of inwall shape and bearing surface side machined surface 48 is processed in the inboard of the pearl pedestal 15 of nib main body 11, and bearing surface side machined surface 48 is formed on from the centre hole side edge of above-mentioned side wall surface to the axle central side and and is connected with centre hole 16.Particularly in the part that forms above-mentioned pressurizing and deformation surface portion 70, be processed into and be provided with the structure of the part of distolateral protrusion (the 2nd operation) forward.Follow again, form groove 47 processing ballpoint tip main bodys 11 (the 3rd operations).Then, place ball 10 in pearl pedestal 15, the front end that makes nib main body 11 is to ball 10 sides distortion (the 4th operation).At last, above-mentioned ball 10 is pressed to centre hole 16 sides from front end, make pressurizing and deformation surface element 70 distortion formation bearing surfaces 45 (the 5th operation) as the part of above-mentioned bearing surface side machined surface 48.
In addition for example, in above-mentioned the 2nd operation, can adopt the part that will form above-mentioned pressurizing and deformation surface portion 70 to be processed into to be provided with frustum of a cone side view the 1st, the summit of this frustum of a cone replaces in the part that forms above-mentioned pressurizing and deformation surface portion 70 for the method for a tool with the front end of point, is processed into the method for the structure that is provided with forward end bulge branch.
In order to increase printing ink flow of the present invention, the front end variant part 43 of the front end of above-mentioned ballpoint tip main body 11 also can adopt the formation of the 2nd mode as shown in Figure 7.
Promptly, as shown in Figure 7, the structure of this ball-point pen tip is that the outer shape of nib main body 11 is for closely coniform, it is ringent pearl pedestal 15 that the inboard of this nib main body 11 has front end, ball 10 places in above-mentioned pearl pedestal 15 and ball and can move vertically at a certain distance in above-mentioned pearl pedestal, has the front end that makes above-mentioned nib main body 11 and is out of shape and the front end variant part 43 of formation to ball 10 sides;
The front end variant part 43 of above-mentioned nib main body 11 has the Outboard Sections 55 that is cut circlewise, and this Outboard Sections and inside part are out of shape to ball 10 sides together.
In addition, as Fig. 7, around the centre hole 16 of ball-point pen tip main body 11, be radial being provided with and be called as the groove 47 of vowing groove.This groove 47 is connected with pearl pedestal 15, and printing ink 5 can be from centre hole 16 by groove 47, and the export department 61 of pearl pedestal 15 sides of the groove 47 of flowing through flows to pearl pedestal 15.Ball 10 is spherical, is maintained in the pearl pedestal 15 of ballpoint tip main body 11 and rotatable.That is, rear end side is by bearing surface 45, and side is by cylindrical wall 41, and front keeps ball 10 by front end crushed element 43, and front end crushed element 43 is after ball 10 inserts, the part that the front end that makes ballpoint tip main body 11 of being closed up is out of shape to the inside.
Above-mentioned pearl pedestal 15 has as being the cylindrical wall 41 of the sidewall of cylinder interior shape, the bearing surface 45 that is positioned at cylindrical wall 41 rear end side and joint face 71.Joint face 71 is the faces that connect cylindrical wall 41 and bearing surface 45.Bearing surface 45 is to form by the pressure pearl that ball 10 is pressed from front thruster to the back-end.The shape of joint face 71 is parts of cone surface, is the mortar shape.
In the ballpoint tip 1 of present embodiment,, as shown in Figure 7, between the front end crushed element 43 of ball 10 and nib main body 11, form gap S1 by pressing pearl ball 10 side shifting to the back-end.In addition, because bearing surface 45 forms its whole formation and the identical shape of the curved surface of ball 10 by the pressure pearl.In use, during to bearing surface 45 thruster pressure ball pearls 10, the integral body of bearing surface 45 contacts with ball 10 from front end.In addition, in Fig. 7, L presses the pearl deflection, is the movable distance by the ball 10 of pressing pearl to cause.
In the time of will more stablely flowing out printing ink 5 more, as shown in Figure 8, be preferably the formation that the inboard that as far as possible makes front end crushed element 43 is short and tilt.Promptly form, with respect to the front end crushed element 43 of ball-point pen tip 1 at radial apart from x, make at axial length y to reduce.By taking such formation, front end variant part 43 more tilts with respect to the axle of ballpoint tip 1.When the inclined degree of this front end variant part 43 was big, the space 66 in the pearl pedestal 15 was big more, and the outflow of printing ink 5 is good more during use.
When making these ballpoint tips, for example the outside of nib main body 11 is processed into nearly cone shape (the 1st operation).Then, the front end in nib main body 11 outsides is cut to ring-type, with above-mentioned cut to cyclic part to ball side distortion (the 2nd operation).Follow, forming front in the inboard of nib main body 11 is ringent pearl pedestal 15 (the 3rd operation) again.Then, make the groove 47 (the 4th operation) that is connected with centre hole 16 by cutting laterally to the centre hole wall.At last, ball 10 is placed in above-mentioned pearl pedestal 15, the front end of nib main body 11 is formed front end variant part 43 (the 5th operations) to the distortion of ball 10 sides.By these a series of operations, can be made into a tool with above-mentioned nib.
In addition, the ballpoint tip main body of above-mentioned embodiment such as above-mentioned, the 1st the shape that is whittled into cyclic Outboard Sections (ring-type is cut the system part) 55 is the side shape of the frustum of a cone, there are corner angle the edge section of the 1st rear end side.When therefore writing with the ballpoint tip of above-mentioned embodiment, the edge of rear end side can be stuck in to be write on the object, has the bad problem of sense of writing.As the ballpoint tip main body that addresses this problem, above-mentioned ring-type is cut the 1st of system portion 55 the curved surface that protrudes laterally that is shaped as.The edge of the 1st rearward end does not have corner angle, and the edge of the 1st rearward end connects glossily, forms continuous face.When therefore use is write by the prepared ballpoint tip of ballpoint tip main body, do not have and block and write the relatively poor problem of sense.
